1 and 2 show the arrangement of members used in the electrodeposit manufacturing method in the splash zone according to the present invention, and in the figures, reference numeral 1
The leg members shown by numeral 2 are electrically conductive leg members that support a structure such as a platform (not shown), and are formed in a cylindrical shape and are suspended from the seabed 2. Reference numeral 3 denotes an absorbent member such as a sponge, which is wrapped around the splash zone of the leg member 1 to surround the splash zone, and impregnates the absorbent member 3 above the sea surface with seawater 4 by capillary action. This makes it possible. 5 is a conductive member such as iron that serves as an electrode;
It is arranged within the absorbent member 3 and around the outer periphery of the leg member 1 . Reference numeral 6 denotes minerals such as CaCO 3 and Mg(OH) 2 , and the conductive member 5 and the leg member 1 are connected to the positive and negative electrodes of a DC power source (not shown), respectively, to generate a weak current (several V, several mA/cm). 2 ) is electrodeposited on the splash zone of the leg member 1 by flowing it.
